Groove TechnologyTo improve airflow through the port of the enclosure, Pioneer engineered the port hole with grooves to help direct the sound waves smoothly. The technique decreases standing waves from the mouth of the port, resulting in smooth bass and midbass output, with more impact.

Convex DiffuserMatching the bass output of the speakers, the soft dome tweeters are set in the center of a convex diffuser optimizing output and dispersing the sound energy in both left and right directions for wider imaging. The blue area below shows the normal spread of sound, and the orange area displays the enhanced spread of sound with the diffuser. For a cool cosmetic look, the diffuser also illuminates in white when the speakers are powered on.

Inputs and ExtrasThe S-DJ50X model features three types of inputs (XLR, TRS and RCA) for connection to different devices such as DJ equipment, computers, and portable devices. For convenience and power conservation, the speakers also include an Auto Standby mode that automatically turns itself off when there is no input signal sensed after 25 minutes and powers back on when signal input is detected.

EQ Controls:The speakers also enable users to adjust high-pass level output via the built-in equalizer from the back of the speaker. The equalizer adjusts the high frequency range in one decibel increments (-2dB to +1dB), tailoring the audio output to the user’s listening preference.
